Might as well toss my hat into the ring, I'm here in Canton, just started tinkering with the Duemilinove and the Mega-2560 in the past few months. Slowly trying to ressurect a robot I began 2 years ago on the VEX platform. (replacing the MCU with the Duemilinove to get things moving, then if expansion is needed (more I/O) the Mega-2560 is sitting & waiting.
